GENERAL DESCRIPTION The ADMV8416 is a monolithic microwave integrated circuit (MMIC), tunable band-pass filter that features a user selectable pass-band frequency. The 3 dB filter bandwidth is approximately 15% of the center frequency (fCENTER), and the 20 dB filter bandwidth is 37%. Additionally, fCENTER can be varied between 6.8 GHz to 16.8 GHz by applying an analog fCENTER tuning
voltage between 0 V to 15 V. The usable pass band corner frequencies (fCORNER) span from 6.3 GHz to 18 GHz. This tunable filter can be used as a much smaller alternative to large switched filter banks and cavity tuned filters. The filter has excellent microphonics due to the monolithic design and provides a dynamically adjustable solution.

THEORY OF OPERATION The ADMV8416 is a MMIC, band-pass filter that features a user-selectable pass-band frequency.
VCTL is control voltage for selecting low or high band-pass filtering. VCTL sets the switch positions for low and high band-pass operation. When VCTL = 0 V, the high band-pass filter is selected, which has an fCENTER range from 12.6 GHz to 16.8 GHz. When VCTL = 2.5 V, the low band-pass filter is selected, which has an fCENTER range from 6.8 GHz to 12 GHz.
The fCENTER is adjustable by supplying VTUNE, which varies from 0 V to 15 V. In typical operation, turn on the level shifter by applying the correct voltage on the VDD pin and VEE pin, then control the switch by supplying the VCTL pin, and lastly, supply the VTUNE for the fCENTER.
TYPICAL APPLICATION CIRCUIT Figure 46 shows the typical application circuit for the ADMV8416. The RFIN pin and RFOUT pin are dc-coupled, and blocking capacitors are required if the RF line potential is not equal to 0 V.
